PROCESSING AND PROPERTIES OF Na0.5Bi0.5TiO3 PIEZOELECTRIC CERAMICS MODIFIED WITH La, Mn AND Fe
Abstract
<jats:p> Although a great deal of work has been done to understand defect chemistry in "soft" and "hard" PZT-based materials, there is little understanding of how defect chemistry influences the properties of lead-free piezoelectric materials. This paper reports a systematic investigation of doping on the ferroelectric and piezoelectric properties in Na <jats:sub>0.5</jats:sub> Bi <jats:sub>0.5</jats:sub> TiO <jats:sub>3</jats:sub> (NBT)-based ceramics. NBT-based ceramics have been synthesized by traditional solid state routes using several different dopants including lanthanum, manganese, and iron in 1 mol%. The addition of iron and manganese lead to an increase in the coercive field (E<jats:sub> c </jats:sub>), a decrease in the piezoelectric coefficient (d<jats:sub>33</jats:sub>), and an increase in the thermal depoling temperature (T<jats:sub> depole </jats:sub>), similar to the behavior of "hard" PZT. Lanthanum, on the other hand, leads to a decrease in the E<jats:sub> c </jats:sub>, an increase in d<jats:sub>33</jats:sub>, and a decrease in T<jats:sub> depole </jats:sub> similar to that seen in "soft" PZT. </jats:p>
